2D Materials

Graphene

Our research efforts on this sheet-like carbon structure consist mostly of covalent and non-covalent modification of graphene and its subsequent spectroscopic and electrochemical characterization.

Our group has been working especially hard on the electrochemical reduction of graphene oxide (GO).  We have successfully followed this reduction process with a number of in situ techniques.  As a result, we are proudly applying our knowledge in joint projects with other groups focused on graphene-based optoelectronics and sensors.

Another field of interest for graphene oxide is its use in bioimaging with transmission electron microscopy or TEM. GO’s qualities, such as high transparency under an electron beam and an affinity for certain biomolecules make it an ideal candidate for a substrate material.

MXene

Our research group has recently started working with MXenes, a new class of 2D materials that have been widely used in energy storage applications. We use MXenes in combination with different conducting polymers (PEDOT, PAz, graphene, etc.,) to make composite materials for supercapacitor fabrication. Additionally, we are also exploring MXene-cellulose composites to form freestanding films to be used as electrodes for supercapacitors. We also study the effect of ionic liquids on the exfoliation of MXenes as well as their use as an electrolyte for MXene/MXene composite-based supercapacitors.
